Galileo seems to be what they are calling the environment the USB boots to. This environment is moving from the XFCE desktop environment to the different KDE plasma desktop environment. These environments can both be customized, but they are very different under the hood. I imagine that you can still choose XFCE and other desktop environments from the installer.
Galileo is the name of the “release”, which while somewhat of a misnomer for a rolling-release distro, is something EndeavourOS has done since the beginning. The current release is called Cassini Nova.
You are correct that EndeavourOS is a rolling release. In that sense, you never have to ( and never really do ) “upgrade” to these new “releases” since you are essentially always using the latest software.
The releases do two things:
1 - they provide updated install media that are closer to the current repo contents so that upgrading after install is a smaller and more reliable operation.
2 - they provide an opportunity to change the system defaults. For example, the move to dracut. If you installed a couple of years ago, you can upgrade all your packages but you will still not be using dracut ( unless you make that change yourself ). Everybody that installs EOS now will use dracut by default. That is true of other things, like this change to KDE for the offline install.

You can only choose the other DE options if you use the “online” installer. By default, you will get KDE now.
